IT is a duty as well as a pleasure to acknowledge the very 

 great assistance given us by the Oological Fraternity in 

 general in bringing the catalog into being. 



To the Committee of Twenty-five who labored earnestly 

 and long with the question of prices, and the final Committee 

 of review, we all owe a debt of lasting gratitude. 



To W. E. Clyde Todd, of The Carnegie Museum of Pitts- 

 burgh, who kindly volunteered to read proof on the scientific 

 names, the publisher is under very special obligations for 

 lifting the burden of responsibility from our busy shoulders. 



To George Miksch Sutton, of the same institution we are 

 likewise obligated for the splendid half-tone drawing of the 

 eggs, illustrative of the proper method of marking. 



R. M. BARNES.
